Hi Steve, I will tell you a big secret; a digital PLL is not a low phase noise system and a very good introduction to PLLs and the digital PLL could be found in Roland Bests: Phase Locked Loops 6/e: Design, Simulation, and Applications 73 KJ6UHN Alex On 10/16/2015 7:45 AM, Martyn Smith

Roland Best's text is the best (no pun intended) one I have seen on PLLs. I didn't know it was up to a sixth edition. On 10/16/2015 11:18 AM, Alexander Pummer wrote: Hi Steve, I will tell you a big secret; a digital PLL is not a low phase noise system and a very good introduction to PLLs and

I have a synchronome clock built for the British Post Office. I find that the 10V or so that a USB to serial adapter can produce can trigger the solenoid, if allowed to charge a capacitor for the intervening minute. The effect is that I can print a single character once a minute at a low bit rate

Meanwhile I like his book better, but the Best book isn't too bad for some people. Wolaver is another good book. They excell in different aspects. Cheers, Magnus On 10/17/2015 12:33 AM, Alexander Pummer wrote: actually my old friend Dr. Floyd Gardner -- who is the pope of the phase locked

I also knew Dr. Gardner in that time frame. I had the responsibility for the specification and procurement of the Saturn V comm system. It included a phase locked turn around offset transponder for Doppler tracking. Also forward command and return telemetry. To gain some knowledge of phase
